Regulated CO2 Piston T-Shirt Cannon

Unread postAuthor: turbohacker » Sat May 26, 2007 10:45 pm

This is another gun built fo the purpose of shooting T-shirts at football games. I have not fired it above 100 psi, however, at 100 psi it will fire a rolled up t-shirt over 350 feet (which is much further than needed) It will shoot about 12 shots on one CO2 tank

That is sick man! It looks like the French APILAS LAW

This is the APILAS LAW:

EDIT: I have got an idea for your next cannon. Make it an almost exact replica of some kind of firearm.

Noice launcher!

I can see the extra lengths in which you went to keep this launcher clean, and professional looking. Butted fittings are very well executed, even though it all ways seems like a threaded joint has to come along and mess up that flow. Like how you used that belled end of the chamber for the transition into the flange. Also got that CO2 system to fit on there nicely. I'm gonna have to buy myself some flanges, and a 90 sprinkler so I can make myself a bazooka style coaxial.

Just a few things. I might have left all the brass fittings, hose clamps, and blowgun un-painted. Also possibly mounted the whole CO2 deal on the non-body side, rather then the top. Again, noice launcher.

Main Pipe is 4"
Barrel is 2.5" and handle (which is not pressurized is 1"
Thanks for your thaught/ complements!
Im thinking of making a for-legged standto mount to it so you could set it down without hitting the CO2 setup
